Hello to all the sifu's out there.

I just bought a 2009 Persona (1st gen, not special editions or elegance) with IAFM. it is a manual h-line. Need to ask for advice here.

1) my brake discs are quite thin. I think these are the original discs from the factory, and now it's not biting well. my dad says can skim but i think it's better to replace. any advice? if need to replace, i don't need performance parts, normal discs can already. any good brake shops to go to?

2) my engine starts to have a tak-tak-tak sound. I think it's the (in)famous iafm problem. Since the sound is quite soft, should I go to a workshop to repair it or should I replace it? for all the bros who replaced their iafm, did the problem come back again?

I was quoted at proton edar larkin in JB that the cost of replacement including labour is RM600+. I read from previous posts that RM300+ can gaodim everything with labour. Is the RM300+ quoted by a service centre? Should I replace at a service centre or go to 3rd party workshop? Is it true that later batches of iafm module uses thicker stronger plastic that won't crack?

3) I saw that there are some recommended service centres in the first post of this thread. any recommended SC's or 3rd party mechanics (good, professional service) in Johor? Likewise, any good, honest stockists in Johor to recommend?

4) can I use 5w30 engine oil in the persona?

So far I have used the car for 3 weeks, fuel consumption is about 12km/L, 30% city 70% highway. Hopefully it can improve after I send for servicing.

Btw I'm from singapore and I just got this car 2nd hand. Not too sure what the previous owner did or did not do but overall seems decent enough. this car is quite cold door here so I was hoping for some lobangs from this thread.

Thank you!

hi shifu's,

thinking of changing to a lighter flywheel for better acceleration. any advice? any shop recommendations which sell aftermarket/custom flywheel?

not much info in the forums about this, and I don't want to skim my original flywheel for obvious safety reasons.

Is it recommended to install lightweight flywheel with a lightened crank pulley together? some forumers said campro crankshaft fragile cannot install lightweight flywheel... o.o

any comments/advice is welcome thanks.
